Bug Fixes in This Version

4995031

5030876

Description: Following a firmware update via the Oobupdate script, the version reported for components such as UEFI may occasionally fail to reflect the newly installed version. This is a transient reading error, not an update failure.

Reported in version: 26.04

4662191

Description: The BMC pending version may be displayed in a non-standard format (e.g., the version BF-26.01-36 may appear as 02601036).

Reported in version: 26.01

4917779

Description: Initiating an Arm GracefulReset can cause the BMC's Redfish UpdateService to incorrectly report its state as UnavailableOffline.

Reported in version: 25.10-LTSU2

4944048

5036009

Description: When upgrading or downgrading between the 25.10-LTSU2 and 26.04 releases, repeated BMC reboots may, in rare cases, cause the profile-manager service to fail due to a malformed JSON file. This failure triggers a core dump of the service, populates core dump logs, and causes the golden-image service to become unresponsive.

Reported in version: 25.10-LTSU2

4917779

Description: Initiating an Arm GracefulReset can cause the BMC's Redfish UpdateService to incorrectly report its state as UnavailableOffline.

Reported in version: 26.01

4948318

4945554

Description: If a secondary BMC task (such as a log dump) is started after the BMC firmware update has been initiated, but before the installer's monitoring logic has attached to it, the installer may mistakenly track the secondary task. This tracking error causes the installer to misjudge the update's completion, which can cause the subsequent BMC reboot to fail and leave the new firmware in a pending, unactivated state.

Reported in version: 26.01

4401488

Description: The BMC kernel enforces CONFIG_STATIC_USERMODEHELPER, which routes all usermode helper calls to /sbin/usermode-helper. Because this executable does not exist on the system, these calls fail and may cause undefined system behavior.

Reported in version: 26.01

4905017

Description: When operating in NIC mode, a host power cycle may intermittently cause the UEFI to fail to retrieve BMC Redfish credentials. This results in a DPU-BMC RF credentials not found error and introduces a timeout delay during the boot sequence.

Reported in version: 26.01

4969243

Description: When the ENABLE_BMC_WAIT flag is active on BlueField-3 DPUs, the BMC SEL may intermittently fail to record the complete UEFI boot progress following a host power cycle. This is a cosmetic issue and does not affect the functionality of the DPU.

Reported in version: 26.01

4995032

Description: Redfish queries via OobUpdate --show_all_version intermittently returned empty strings for IPMB-backed properties (such as BOARD and BSP).

Reported in version: 26.01

4867786

Description: During BFB installation, the Golden ARM image update may intermittently hang and fail via Redfish, logging a golden_image_arm firmware update timed out error.

Reported in version: 26.01

4914053

Description: The BFB installer defaults to DHCP for the VLAN4040 interface. If no DHCP server is present, the request silently fails after a 300-second timeout, bypassing the static IP fallback and skipping all BMC-related firmware updates.

Reported in version: 26.01

4924426

Description: Following a DPU reset, the BaseMAC, BaseGUID, and Description fields may incorrectly return as empty within the redfish/v1/Systems/Bluefield/Oem/Nvidia schema response.

Reported in version: 26.01

4987307

Description: During BFB installations via Redfish, the task state may change to "Exception" before the specific error message is appended to the HTTP response payload. This results in incomplete error logs on the initial poll following a failure.

Reported in version: 26.01

4980118

Description: The set_emu_params.sh script attempts to load the mlxbf_ptm (DPU Power Telemetry) driver, leading to continuous module load failures and log spam because mlxbf_ptm is a non-upstreamed debug driver that is unsupported on several operating systems.

Reported in version: 26.01

4799519

Description: Accessing the /redfish/v1/Managers/Bluefield_BMC Redfish endpoint may time out, accompanied by repeated ipmb-host timeout errors in the console and significant delays (multiple minutes) when opening the UEFI "System Configuration" page.

Reported in version: 26.01

4932328

Description: Excessive Common Platform Error Record (CPER) files in /var/cper can exhaust the BMC root partition space. This crashes the entity-manager service and causes IPMI commands like ipmitool sdr to fail.

Reported in version: 26.01

4957197

Description: When external monitoring tools or scripts repeatedly query the BMC's Redfish interface using Basic authentication over extended periods, internal session resources fail to release properly. This memory leak eventually causes the BMC to lose network connectivity, even while the DPU management interface remains online.

Reported in version: 26.01

4966472

Description: The BMC generates a warning log for PLDM_Sensor_1_100 when the NIC temperature reaches the official 91°C upper non-critical threshold. This is an expected hardware alert for elevated temperatures, not a software defect.

Reported in version: 26.01
